This is a big part of the problem. The incentives.

There is no blank space to fill with something useful.

Instead everything is filled with SEO driven, ad riddled, bullshit.

And creating something useful is more cost and effort than creating more SEO driven crap.

And even if you do create something useful, you’d then need to focus on SEO in order to compete.

There’s no way this problem isn’t solvable. But google seems to lack any motivation to solve it.
